I have been an endurance athlete/triathlete my entire life. My perfect Saturday was a 45-mile bike ride, followed by an 8-mile run with a 5 hours rest afterwards and then an afternoon masters swim chased with several pints at the La Jolla Brewing Co. I always thought that my activity would make me bulletproof, and I'd live to be 100. 2 years ago, after a vigorous masters swim in the lead lane with an ex-olympian, holding times that I would be proud of in my 20's and 30's,- I went home, had a sandwich, sat down at my desk and (with no prior history - family or otherwise) had a heart attack. They told me it was SCAD (Spontaneous Coronary Arterial Dissection) It was a super rare type of heart attack that effects women having a baby (90%) and endurance athletes (10% male). It floored me. I asked my Cardiologist "what caused this?" he said - "I don't know". I asked, "Will it happen again?" he said - "I don't know". I now hang in the back, I am at about 65% of where I was 3 years ago, I take long walks and am enjoying the view from the middle/back of the pack. I'll be 60 next year, and I know my kids would like to see another 40 more.

[@DrGFS]

for those who don't have a spare 18 rambling minutes of time this is the conclusion from Dr O'Keefe's paper: The take home message for most is to limit one’s vigorous exercise to 30- 50 min/day. If one really wants to do a marathon or full-distance triathlon etc, it may be best to do just one or a few and then proceed to safer and healthier exercise patterns. On the other hand, light or moderate intensity exercise does not present the dose-dependent risks associated with excessive endurance exercise. A routine of moderate physical activity will add life to your years, as well as years to your life. In contrast, running too fast, too far, and for too many years may speed one’s progress towards the finish line of life.

I wonder how much of the deleterious effects of "endurance exercise" is more from the high carb diet which is so endemic in that culture rather than the effects of overtrainig? Add to that the addition of all the sports drinks and gels and their insulin levels must be over the top. Insulin Resistance is now widely recognized to be the root cause of cardiovascular disease as well as most other degenerative diseases.

I think a reason many people train too hard is because of things like they want to "lose weight." So they run more than they should a day. It should be a lifestyle, not a temporary thing. And there is no hurry when you make it a permanent lifestyle change as long as you make progress in reaching your goals.

I'm 37 now, and I've been running since I was 14. Nowadays, I average 25 miles per week, but when I was in my teens and twenties, I used to run even more, like 35-45 miles a week. Once I entered my 30s, I purposely reduced the time spent running to incorporate more of strength training programs, such as weights, HIIT, and pilates. I've never ran a full marathon in my life - I never saw the point of it. I ran a half marathon once out of curiosity, and never felt the need to run more races. I feel and look pretty good now. I think the amount of running I'm currently doing is especially necessary for my mental well-being.

My usual run is about 30 mins/day 4 or 5 days/week. I do some short sprints of 200m in those runs however with walking recoveries until my heart rate gets back to 70% of max which is when I start the next 200m interval.

[@juliaangelina1984]

The fact that this is controversial, and that people don't intrinsically understand that exhausting the machinery on a routine basis can be damaging just goes to show how removed from reality we are when it comes to our ideas of "fitness." We have young celebrity women with extreme diet and exercise routines and super thin frames coming out with fragile bones, osteopenia, diseases of weak, older women, and we still say "oh but they're so fit!" We worship diet and exercise, more is better because we're all such lazy fatasses or whatever. Look. We'd do good to get off the couch and eat less crap but we don't have to run marathons or claim to think a green juice is all you need for satisfying lunch. We could go back to a moderate pace of activity, moderate meals, and occasional bursts of high-intensity exercise and we would gain back all the health we lost in the past 60 years. Marathon runner's arteries hardening is probably due to the same process anyone else's harden: inflammation. Inflammation is not only caused by a sedentary lifestyle. It's also caused by an extremely stressful one, and marathons, no matter how much runner's high endorphins your body pumps out to keep you from feeling the intense pain you're actually in, are extraordinarily stressful on the body.

Running "hard" and "pushing it" at an exhausting pace for 12 miles however is extremely different, and only gets more intense at higher distances, and this is more where this cardiologists research gives evidence. I knew runners who simply didn't know how to take it easy and would push hard and exhaust themselves on both the easy and the hard days, and it seems like this cardiologist's friend was one of these guys "felt like a wimp when he couldn't toughen out 12 miles".

I suppose the "ability" to work hard-play hard is a dubious strength. 50,000+ participants in the study would suggest that random dietary differences would be canceled out by sheer sample size, but it's certainly not a random sample, so diet could account for (some of) the differences. Thanks for your comment.

How’s this doctor doing today … 10 years later? Does he have new insights?

[@terryderoulet3076]

I disliked that the doctor started with individual accounts of heart attacks. He starts with Phidippides, who actually ran 2 marathons that day. As a doctor myself, we call this persuading by fear. As the Running News editor asked, Where are all the bodies? Vigorous exercise did offer more mortality protection than a lower level of exercise, but it wasn't quantified for us. It seems Iikely from recent reports that the "no pain, no gain" approach to long distance sports may be the culprit. It appears that using the MAF method of training, which keeps people mainly within their aerobic capacity, doesn't cause the same stress on the heart, and that even marathons can be approached safely. At the end, there were still no guidelines as to how to get the best, safest results for exercise. This talk discouraged me from running for years until I re-watched it. Now I've gone back to running, but I'll also have my heart evaluated periodically to assess how it's tolerating my own prescription.

[@dcrock8978]

Agreed, the doctor made many presumptions based off of minimal studies, small sample sizes, and no studies specifically targeted at different heart rate zones and times. Did get a few nuggets though, but unfortunately he made conclusions that just aren’t accurate.

[@RLekhy]

Long ago Buddha suggested not to go extreme. Too much eating and not eating, too much sleeping and not sleeping... Just like a string musical instrument, too tension can break the strings and not tensed strings can't make musics, similar our life should be fine tuned, and this fine tune comes from practice and intuition, science can give extra flavor.

[@rjf7023]

data aside, it just makes common sense to think that too much exercise would be bad for you because humans weren't designed for that.. we evolved to run hard fast and for short spurts to get away from prey. When in nature would you be required to run away from something at a 'comfortable pace' for 2 hours+ ? , either you run hard and fast and get up a tree or in a cave to safety etc or you get caught and the bear/lion eats you.

While the research displayed in this video is important, I think it ignores the true motivators for people who compete in marathons and ultra-distance sporting events. Generally, someone running only for health benefits would see no reason to exceed 25mpw of training. Those who choose to make running a passion, and therefore participate in excess, do so for an entire myriad of reasons that typically stem from the heart of who they are as an individual and the type of person they want to become. I've never met someone at an ultramarathon who claimed to be competing for their health; we aren't that naive. For me, the innate desire to get the best mental and physical performance out of my body far exceeds any worries I have over the condition of my heart.

[@vishvajeetsinh_solanki]

*Excuse me. Why did you miss one thing in your so precious study: Food? What kind of food your research participants were taking? Just because they could run, doesn't necessarily I have to believe that they were on good diet.

[@philiphusband2860]

His focus on exercise intensity is very important: At 35, I had a comprehensive heart examination, including EKG, ultrasound and wearing a Holter monitor for 24 hours. The doctors could find nothing wrong with me. A few years later, I tried a high intensity interval workout which included eight 30 second sprints within a 20 minute period, during which I pushed myself to the limit. At the end of the workout, my heart rate didn't slow down as it normally would, making me feel dizzy, uncomfortable and very scared. This phenomenon is called exercise induced tachycardia. After 10 minutes or so, it subsided, but I would never push myself so hard again - it's just not worth it.

To be fair, you weren't adapted to this type of workout. All evidence for decades has been that you shouldn't just "max out" without training. This is regardless of the exercise. This TED Talk doesn't comment on HiiT, sprints, or strength training. It doesn't even discuss things like 400m or 800m sprints. Just mid to long distance training. If you don't ever do sprints again, that is perfectly fine. But I wanted to clarify things for others who read your story and think it's proper evidence to avoid high intensity workings.

​@@Zyberwoof (wanted to point out that the video did not address the effects of combining various running times and distances with weights training, and I'd like to see that) anyhow, I know someone who had palpitations after/during exercise.

We are meant to run. You cant tell the whole population to run a specific pace because pace is individual.

Take this with a grain of salt and do your own research. Just like with diets there are multiple sides to the story and numerous research articles. Ultrarunning and ultra endurance sports, strengthen the body, the mind, improve depression symptoms, strengthen your joints, muscles (when trails and elevation get involved).

I’m an accomplished runner an I’m asking if he knows why 1800 is so far off the scale? Endurance events provide record breaking results all the time. For example, recently lactic acid in the blood stream NOW is used as a fuel source for he body and is NOT detrimental. I have been very active for 40 years since high school and I can attest the my waistline and number of grey hairs was significantly less than my school mates. Running does add life to the years.

I strongly agree with this. I've always ran and love it but I have to agree that it really makes sense. Pushing too hard or fast is not optimal, but in the other hand it's not about not exercising but just do it slower and with less intensity.

She ran so much that her body was swelling on the inside and she went blind because the swelling was pressing on her optic nerve. Did she stop? No, she stumbled and fell the rest of the way. If you look at some runners they look a lot older than they are. Some people get addicted. Longer isn't always better.

Maybe below that limit (you can run with the mouth shut) the heart goes confortably and it is like going for a walk? It is a pity they didnt take into account hr zones in that study. I could train wrong for endurance and go 2 hours every week in anaerobic because i am used to that suffering and i can do it resting later 2 days. Most of people do that. Dont they?
